Diffrerential Photon-Jet Cross-Section Measurement with the CMS Detector at 7 TeV

The associated production of a photon and one or more jets in pp collisions provides a direct probe into the hard QCD interaction, is sensitive to gluon densities in the proton, and is a major source of background to standard model searches. A measurement of the differential cross section in final states with photon and jet is presented using data collected with the CMS detector at 7 TeV at the LHC. The measured distributions are corrected for efficiency and unfolded for detector effects to be compared with results from event generators. Theoretical predictions are found to be consistent with measured cross-section within total uncertainty.
